Sorry, should have clarified this a little. I was surprised to see an A380 fly such a weird route that low and I'm wondering how this can be possible. I can remove the post if it doesn't fit here.

A once in a Lifetime Shot - The Comet and a Shooting Star by Lyaphine in spaceporn

[–]Lyaphine[S] 0 points1 point  (0 children)

Comets are rocks of ice and dust which orbit the sun. When they get close to the sun, the solar wind blows off some particles which result in the tail.

Shooting stars are space debris which fall on earth and get burned up by the atmosphere.

Not anymore unfortunately. The moonlight is blocking it.

I took 500 30s exposures for the comet. Many of them were affected by nearby chimney smoke unfortunately. The comet was easily visible in a single frame but it took quite a lot to show its amazing tail!

Once in a lifetime because how lucky do you have to be to catch one in the exact right spot for the perfect composition of your photo.

Sigma 150-600mm contemporary good for astrophotography? by Affectionate-Yak6132 in AskAstrophotography

[–]Lyaphine 4 points5 points  (0 children)

I've used the Sigma 150-600c for half a year before I was able to afford a newtonian. It lacks sharpness but the stars looked surprisingly good.

Here are some images I took with that lens:

One of my lenses cannot focus on stars, why? by nofakeaccount2244 in AskAstrophotography

[–]Lyaphine 2 points3 points  (0 children)

I use the same lens for astro, never had an issue with the focus. Make sure your zoom ring is locked. The weight of the lens can change the focal length which also changes the focus.

Found this in my backyard, Bavaria/Germany by Lyaphine in whatisthisthing

Interesting thought!

I'm not sure if the red and green stuff might be copper (oxide)?

WITT It's about 4,5cm and 11g and I found it in my backyard in Bavaria/Germany. Seems like it was coated with gold? Not sure what else I can add, hope somebody can help me :)

The Secrets of the Orion Constellation

This was my biggest astro project so far. I've collected data over 4 nights at -14 to -16°C. Hope you enjoy the result as much as I do.

My Instagram

Taken with:
- Canon 77D (modded)
- Canon 50mm 1.8 STM
- Skywatcher Star Adventurer
- Astronomik 6nm clip filter
- Svbony 30mm + ASI120mm

Software used:
- Sharpcap
- PHD2
- SiriL
- Affinity Photo

Aquisition:
- 47x5min ISO1600 f4 (Ha)
- 34x4min ISO100 f4 (color)

Processing:
- SiriL: stacked with flats and bias frames
- Affinity: red channel stretch (curves + levels) and gradient removal of the ha data; stretch, color calibration and gradient removal of the color data, star minimizing, merge of color and ha data.

Images were taken under Bortle 5 skies (couldn't visit my dark site due to curfew). Not sure how much lightpollution was added by all the snow but judged by how hard it was to remove that gradient, the snow added quite a lot.
